Specification of Letters Patent.

To all whom t may concern.'

Be it known that I, FRED LoNGT-HORNE, subject of the King of Great Britain, residing at Underclitte, near Bradford, inthe county of York and Kingdom of England, have invented certain new and useful Improvements in the Processes of Producing Intermittently-Dyed Yarn, of which the following is a specification.

The present invention relates to an iniproved process for coloring textile fiber.

The invention is particularly applicable to the coloring or dyeing of fiber when it is in the state of a combed sliver, with a view to producing n'ilange7 and the like yarns.

It has been usual to produce these yarns by causing the sliver to pass to a rotating printing roller which compressed a lateral band of color upon the sliver at predetermined spaced distances along it. It has been found, however that this has the disadvantage that the band of color so impressed is deeper at the point where the printing surface leaves the sliver than at other parts, giving an irregular or non-uniform result.

By the arrangement of the present inven- .tion a band, spot; strip or the like of color 1s impressed upon a textile sliver before it has reachedthe stage of a twisted yarn by a reciprocating action so that color is im pressed evenly upon the whole sliver surface so impressed.

This invention is more particularly described with reference to the accompanying drawing showing an arrangement of a gill box combined with a dabbing device according to the present invention in end elevation.l

A sliver 1 passing from a gill box 2 is conveyed tothe dabbing device of the present invention by conveyers 17 and 18. It then passes over a roller 5 which is permanently in contact with a color distributing roller 6 partly immersed in a'color trough 7 A roller 8 removes the excess of color from the. roller 5. The sliver 1 is brought into Contact with the roller 5 from time to ltime according to a. predetermined rule by a reciprocating plunger 9 mounted adjustably on a spindle 10 which is reciprocated from a crank on the shaft of a gear wheel driven by gearing 12, 13, 14, 15, from a shaft 16 the apron 4 conveys the sliver to receiving carriage 19 mounted on rails 3.

In another arrangement a pad having an inked surface may be adapted to descend from time to time upon the sliver as -it passes under it, which vpad may receive fresh supplies of color from an inking roller pass ing over its surface from time to time or in any other suitable manner.

Either the printing surface itself or the abutment member acting as a counter-sur face, between which surfaces the liber is temporarily held during printing, may be clastically mounted, either pneumatically or on springs, in order to yield resiliently to the printing impression or blow.

It is obvious that one or more of Such printing devices may be arranged either in series or in parallel to one another, acting on the band of combed fiber, or one or more of said devices may be arranged to act on parallel bands of combed fiber, which may then move on to subsequent requisite processes to form mixed colored yarn.

I declare, that what I claim is l. A process of coloring textile fiber, coinprising forming a combed sliver of the fiber, and applying color thereto intermittently by a reciprocating action.

2. A process of forming mlange yarn comprising forming a combed sliver of the fiber, applying color thereto intermittently by a reclprocating action, and `subsequently twisting said sliver into a yarn.

3. A process of forming mlange yarn comprising forming a combed sliver of the] fiber, applying spots of color thereto by a reciprocating act-ion7 and subsequently forming said sliver into a yarn.

1. A process of forming mlange yarn comprising forming a combed sliver of the fiber, moving the same continuously, applying spots of color thereto interniittently by a reciprocating act-ion, and subsequently forming said sliver into a yarn.

In witness whereof, I have hereunto signed my name this 18th day of March 1919, in the presence of two subscribing witnesses.

FRED LoNGTHoRNE.
